That gap is dangerous in an environment where developers are already suffering tool fatigue managing a queue of linters, security scanners, and CI checks competing for attention.
When an AI assistant suggests a fix that turns a failing accessibility check green, it's tempting to accept it and move on — the fix looks reasonable, the build passes, and the queue gets shorter.
But greening the scanner isn't the same as fixing the problem.
